7 claims. (c1. 292-275) This invention relates to a fastening device for hinged building elements, such as Casement windows or shutters. YAn object is to' provide a simple and positively eifective device for adjustably holding such hinged elements in open positions.

Another object is to provide a Casement window fastener, the parts of which are entirely concealed from view and fully protected against being damaged, when the window is closed.

Another object is to provide a easement window fastener, so arranged that the window cannot be accidentally locked thereby in a closed position, as against the window frame.

Other objects and features will become apparent from the following description, relating to the accompanying drawing, showing a preferred form. The essential characteristics are summarized in the claims.

Referring to the drawing, Fig. 1 is a perspective view showing the lower portion of a casement window and frame with the window in partially opened position, as retained by the fastener hereof; Fig. 2 is a horizontal sectional plan view,

2 taken through the lower window sash rail and window stool at the position of attachment of the device, and showing the parts of the device in central longitudinal section; Fig. 3 is a sectional View, taken at right angles to Fig. 2, as indicated by the line 3--3 on Fig. 2; Fig. 4 is a detailed front elevation of the preferred locking mechanism of the fastener.

Referring further to the drawing, the conventional window frame parts, portions only of which are shown, may comprise a vertical side window frame member A, and lower window frame member or sill B having the usual abutment device or stool C, against which the lower edge of the window closes. The window D has one of its vertical sash bars hinged to the vertical framework of the opening, as at F, and the lower sash rail G closes against the stool C.

l The retaining device may comprise, in part, a

rectangular box-like casing I, made of suitable non-corrosive sheet-metal, (e. g. brass), having inner and top walls 3 and 4, respectively, which abut adjacent surfaces of a generally rectangular step, notch or recess cut into the lower sash rail G. Flange portions 3a and 4a. of the casing may overlap the lower and inner surfaces of the rail as shown. The end walls 5 of the casing I may comprise overlapped and joined end ange portions of the sheet-metal walls 3 and 4; or the ends may be formed by drawing the metal in appropriate dies. Any suitable means may be em- The exposed web of the channel may be roughened or transversely serrated as at 9. The channel may be secured to the wall 3 of the casing, as by rivets I0. v

Slidable along the guide 8, I have shown a sho I2, rectangular in shape, which s lidably nts the guide, being retained by the flanges 8a. A bracket I4 formed as a channel shaped sheet-metal section, havingk outwardly extending spaced flanges or ears Illa., has its web secured to the strip I3 as by rivets I5. The shoe is arranged to be locked in the guideway in any position along it.

. The locking arrangement, as shown, comprises a floating key 20, adapted to move in and outV freely in an opening 2l, provided in the web. of the channel I4, and extending through the shoe strip I2. This is arranged to be pressed against the serrated surface 9 of the guide, and, to operate it there is shown an arm 22, pivoted as on a pin 23, to the anges Illa. The arm has an eccentric or cam surface 25, adjacent its pivot, which, d

in one swung position of the arm (e. g. outwardly, see Fig. 1), engages the key 20 and forcesvit against the roughened surface 9.

It may be mentioned that the inner face of the key 20, which grips the web of the channel 8 may be roughened in a manner complementary to the roughened surface 9 of the channel; or the gripping face of the key may be of any other form as desired. When the arm 22 is moved'into the position shown in Fig. 2, the key 20 is entirely released and then the shoe I2 can be slid freely from one end of the guide channel to the other. The locking arm may have side wings 26 at its free end to assist in grasping the arm by the human ngers.

When the lower rail G of the sash rests against the stool C, the arm 22 is retainedvery effectively in key-releasing position because of the juxtaposition of the arm and outer stool surface, as illustrated in Fig. 2; it being necessary to swing the arm toward the position shown in order to release and permit closing of the window in the first place.

For connecting the shoeY I2 and its locking mechanism to the window frame, I provide a substantially rigid link or strut 30, the outer end of which extends between the flanges Illa of the channel M and is pivoted thereto as by a pin or rivet 3l. The opposite end of the bar 30 is similarly pinned as at 32 to a bracket 33 adapted to be fastened as by screws 34 to the window frame stool. The link is of suicient length to permit the Window to be swung open about its hinges the maximum desired distance, and, as Will be seen from the above, the Window may be held in any intermediate desired position by locking the shoe l2 in respective positions along the channel. In some instances, the channel or casing may be made longer than in others, and likewise the length of the link or strut 30 may vary in length and stiffness for diierent installations. It will also be seen that when the Window sash is closed against the stool, the link 30 and its attaohing member is elfectively concealed Within the chamber formed by the casing l in cooperation with the Window frame. It has been mentioned that parts of the device are preferably made of suitable non-corrosive metal. All of the numbered parts may be made, for example, of brass.

I claim:

1. A fastener for Windows or shutters of the easement type, comprising a releasable slide lock set into a step formed in one edge of the Window, a link connecting the lock with the frame for such window, said lock having a releasing part which is held in lock releasing position by an adjacent portion of the Window frame in the closed position of the Window.

2. In a easement Window, a fastener, comprising a guide adapted to be secured in a step formed in the bottom inner edge of the lower sash bar of such easement window, a slidable manually releasable lock cooperating with the guide and settable in various positions along it, an arm for operating the lock, said arm being swingable into a lock releasing position in which it does not project from said edge, and a lock operating position in which it projects from said edge, and a link pivotally attached to the lock and having one end adapted to be secured to the Window frame.

3. A Casement Window fastener, adapted to be housed in a step formed in a horizontal edge of the Window sash, said fastener comprising a guide xed in such step having guideways opposed to each other in a vertical plane, a shoe slidable on the guide, releasable means including an eccentric adapted to bear operatively on the guide and to move horizontally free of the guide for holding the shoe in various positions along the guide, and a link pivotally connecting the shoe With a xed part of the window frame.

4. A easement Window fastener, comprising a channel-shaped guide adapted to be secured to a Window sash, a shoe slidable along the channel, a key carried by the shoe and having free movement in the shoe perpendicular to the web of the channel, an eccentric mounted on the shoe and independent of the key for actuating said key and causing it to engage the web of the channel, and means pivotally connecting the shoe to the windovv frame.
